PG Test for Dogs

If you have a female dog and are trying to determine if she is going to have a litter of puppies and are not sure when to expect the puppies, there is an easy way to find out. A pregnancy test for dogs allows you to detect if your female dog is pregnant.

What is a PG test for dogs?

A pregnancy test for dogs is a diagnostic tool that veterinarians use to determine if a dog is pregnant. It’s often abbreviated as a PG test. A blood test is most commonly used, but other types of pregnancy tests are available.

What are the different types of pregnancy tests for dogs?

There are three main types of pregnancy tests used by veterinarians:

  • Blood test
  • X-ray
  • Ultrasound

Blood Test: Blood tests can detect if a dog is pregnant within one to two weeks after breeding. They are usually done in combination with an ultrasound to confirm the pregnancy. Blood tests are also used to check for hormonal changes that can indicate if a dog is about to go into heat.

X-Ray: X-rays can often be used between 30 and 45 days after conception, but they are not as effective at detecting puppies before this time because their skeletons will not have formed yet.

Ultrasound: An ultrasound uses sound waves to create an image of the puppies inside your dog’s uterus. It’s usually performed between 20 and 30 days after mating, which allows the veterinarian to count the number of puppies and determine whether the dog is carrying more than one litter (which may mean she was mated by two different males).

How is a PG test performed?

A small sample of blood will be taken from your dog and sent to a laboratory for analysis. The results are usually available within 24 hours.

What does a PG test reveal about my dog’s pregnancy?

A pregnancy test for dogs is a blood test that measures a specific hormone known as relaxin. Relaxin is only produced during pregnancy, so if this hormone is present in your dog’s blood, it means she is pregnant. The PG test can be performed as early as 20 days after conception and will be positive by day 30 of the pregnancy.

Pregnancy testing has many benefits. You can plan ahead for whelping if you know when the puppies are due. If you want to sell puppies or plan to enter your dog in a show, knowing when pups are due will allow you to schedule breeding appropriately. Testing allows you to determine if your dog is pregnant before you would be able to palpate her belly and feel the fetuses. This may be important as some small or toy breeds may abort their litter if they are too large for their pelvis size (a condition known as dystocia).

How much does a dog pregnancy test cost?

The cost of dog pregnancy tests varies depending on whether they are bought over the counter or used in a veterinary clinic.

An over-the-counter pregnancy test can cost as little as $20, while a vet-administered test can cost between $100 and $200.

The tests work by measuring the amount of a hormone called relaxin that is produced during pregnancy in a dog’s blood. They can be used to detect pregnancy as early as 15 days after breeding, but are considered most accurate between 25 and 30 days.

Can you do an at-home pregnancy test on a dog?

While it is possible to use an at-home pregnancy test kit on your dog, its accuracy will be limited. In other words, the odds of a false positive or false negative result are extremely high.

There are more advanced pregnancy tests available at veterinary hospitals that can help determine your dog’s status with greater precision. If you think your dog might be pregnant and want to get definitive results, we recommend visiting a vet for a blood test or ultrasound.

How can you tell if a dog is pregnant without going to the vet?

If a dog is pregnant, it’s important to know when the big day arrives. For most dogs, this will be about 63 days after conception. This is the average range for puppies to arrive, but there are exceptions. Some puppies have even been known to be born 70 days from conception.

There are several ways to help tell if a dog is pregnant without going to the vet:

Behavioral Changes

When a dog becomes pregnant, its behavior may change noticeably. She may become irritable and not want to participate in activities that she used to enjoy. She may also become less interested in her food and water. As she gets closer to giving birth, she will probably seem anxious and nervous. She may also begin nesting by seeking out quiet places around the home or yard where she could give birth

Physical Changes

There are also some physical signs that may indicate a pregnancy, including:

  • Weight gain – your dog should gain between 20 and 40 pounds during her pregnancy. Most of this weight will come in the last few weeks of pregnancy, so it’s easy to miss early on.
  • Enlarged nipples – her nipples will begin swelling and darkening as they fill with blood and prepare for milk production.
  • Swollen vulva – At around 38 to 42 days, your dog’s vulva will usually swell noticeably (if you don’t notice the swelling at first, you may become aware of an unusual odor)

Conclusion of pg test for dogs

The only way to know for sure if your dog is pregnant is by having a veterinarian confirm it. They can do this with a few different methods.

  • Ultrasound
  • X-ray
  • Hormone test

The first two methods are fairly accurate, but the hormone test is 100% correct, and it’s the best way to determine pregnancy.

A veterinarian can use an ultrasound to detect a pregnancy as early as 20 days in. An X-ray will work later on, but they aren’t the most effective methods, and they’re not always available to your veterinarian.
